To all whom it may concern:

Be it known that I, WHITNEY B. J one, a citizen of the United States, residing at .Perth Amboy, in ,the county of..Middlesex and State of New Jersey, have invented certain' new and useful gmprovements in Phenolic Condensation roducts, of which the following is a specification. f

This invention relates to afnew composition of matter, the same containing a phenolic condensation product containing methylene groups and a celluloseester or a mixture of such esters, and characterized by possessing a marked degree of flexibility and toughness. Y v

The cellulose ester may be introduced at any stage of the reaction prior. to the final hardening, and may be used in variable proportions, according to the effect v desired. The reaction may be stopped or interrupted desired stage, and the composition materials for molding purposes, or may be dissolved in suitable solvents for the preparation of lacquers, enamels or similar coating compositions. a

A preferred method of preparing the new composition is as follows '-212 grams of phenol or any of its homologues or mixtures thereof are warmed with 25 grams of commercial' cellulose acetate. It is advantageous to add to the solution of phenol and cellulose acetate, either phenylor "cresyl acetate or other suitable phenol-ester, preferably in amount abOut equal to the-quantity of cellulose acetate used. After thesolution is complete, there are added 212 grams of commercial formaldehyde solution, and five cubic centimeters of strong ammonia solution. The mixture is then boiled for two to three hours until separation of water takes place, indicating the completion ,of the first stage of the reaction. Boilingis then interrupted and the water decanted, or the water may be otherwise removed. Heat is again applie and the boiling continued to distil off part* or all of the residual water, the heating being continued until the mass has reached the desired c0nsistence.:

Obviously, instead of aqueous formaldehyde, or formaldehyde and ammonia, I may use any recognized equivalents thereof, such as. hexamethylenetetramin and the like.

. Other cellulose :esters, as cellulose formate,

may be found capable ofreplacing the acetate, either wholly or in part.

" If it is desired to prepare a mass for incorporation with filling materials, the composition is preferably removed from the boiling vessel and rapidly cooled.

enamel, there is added to the hot mass, preferably in the boiling vessel, any suitable solvent or mixture of solvents, it being desirable but not in all cases essential that the boiling-point of at least one of the solvents used If it is desired to" produce a varnish 'or.

should be higher than that of water. a As cooled, yielding a clear, thick liquid varnishor enamel. This varnish may be further diluted to any desired consistence by appropriate solvents, and may,"if desired, have added thereto suitable pigments or-filling materials for the-production of certain protective coatings or enamels.

When applied to metallic or other surfaces and properly very tough coating which resists the action of organic solvents, dilute acids, etc, It may likewise be such solvent, I prefer "to use tetrachldr ethane, but any other suitable solvent orbaked, this. lacquer forms a hard, highly-flexible and applied to absorbent materials or surfaces with excellent results. I

The expression phenolic condensation product, as employed in the claims, is intended to.includesuch condensation products of equivalents as have been renderedinsoluble and also such condensation products as are soluble and fusible, whether capable or not of. transformation by simple heating into insoluble products.

The expressions as herein employediare phenoland formaldehydeor their.

cellulose ester and intended to include any definite cellulose -I esters or the usual commercial products containing a mixture of such-esters.

Iclaim: v1. As a new composition of matter, a

liquid coating composition containing a condensation product and acelluin conjunction with a solvent hav-f ing a boiling-point higher than that of water.

2. As a new composition of matter, a coat-' .ing composition containing a phenolic condensatlon product and a cellulose ester, 1n

conjunction with a solvent containing -a chlorinated hydrocarbon.

3. Asa new composition of matter, a coatdensation product and a cellulose ester, in

conjunction with tetrachlorethane.

5. As a new composition of" matter, a phenolic condensation product containing a cellulose ester'and an'es'terof a phenolic phenolic condensation product containing mosses cellulose acetate and an acetate of a phenolic body.

7 As a new composition of matter, a coating composition containing in solution a. phenolic condensation product, cellulose acetate, and an acetate of a phenolic body.

8. Asa new composition of matter, a liquid coating composition containing a phenolic condensation product, a cellulose ester, an ester of a phenolic body, and a suitable solvent.

9. As a new composition of matter, a liquid coating composition containing a phenolic condensation product, a cellulose ester, an ester of a phenolic body, and tetrachlorethane.

In testimony whereof I aflixmy signature in presence of two witnesses.
